Any advice is helpful

Whew, this is great stuff, but I have the impression that no matter what I post, Brom, you are going to consider it short of a cogent argument. You are speaking in absolutes--but even then only sometimes. For instance, I specifically stated that wine offers minerals (trace minerals) and some vitamin (minuscule as they are). That is food to me. yet you chose to ignore that portion of my comment. Beer offers some of the same things as wine (I suspect the yeast cells dump a small amount of protein into each drink too). As for Bloody Mary, I think (but am not equipped to prove it) that the tomato juice is the food part...

And it is true that you cannot live for long on one food-unless that food contains every nutrient the body needs. Can you prove otherwise? I'd like to hear about it.

The potato is considered a whole food: protein, carbs, calories, minerals, vitamins, et al, but even the potato will come up short. For instance, it will not prevent scurvy, and that can kill you.
